How to globally replace pipe symbol "|" in string

Question

How can I globally replace the | (pipe) symbol in a string? When I try to replace it with "so|me|str|ing".replace(/|/g, '-'), I get "-s-o-|-m-e-|-s-t-r-|-i-n-g-"

Answer 1

| has special meaning (A|B means "match A or B"), so you need to escape it:

"so|me|str|ing".replace(/\|/g, '-');
